This is a very simple board that takes a 6-12V input voltage and outputs a selectable 5V or 3.3V regulated voltage. All headers are 0.1" pitch for simple insertion into a breadboard.
Input power can be supplied to either the DC barrel jack or the two pin header labeled + and -. Output power is supplied to the pins labeled GND and VCC. Board has both an On/Off switch and a voltage select switch (3.3V/5V).
The two sets of four GND and VCC holes are spaced such that when connected to our Basic Breadboard both power busses will be powered.
Note: Headers are not supplied. You will need to supply your own headers to connect this board to a breadboard. Check below for some breakaway header strips.
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Having a few of these lying around makes it easy to quickly try something or leave something with a supply handy.

This wonderful little board let's me choose 3.3V for a Particle board or 5V for an arduino and the extra header let's me pull off the source 12V.
I have only recently begun working on electronics projects. This power supply works well for my needs. I mostly need 5 volts, for my breadboard for small projects.
I soldered four header pins into the board and that was that. I pushed into the breadboard easily. There is an on-off switch and a switch to go from 3 volts to 5 volts.
Works great. Very happy with it for the price.
This is a great board, add on for using a breadboard. Especially when needing 5 or 3.3 volts. Easy to solder the pins. The only complaint that I might have is that the on/off switch is small. Great board. I love it.
This is a great little power supply. I'm using it regularly. The surface-mounted ON/OFF and voltage switches are convenient as is the generous supply of PCB holes for .1" pins.
My only complaint would be about the lack of mounting holes. From the name, I assume that the board is meant to be plugged into a solderless breadboard. But unless I missed something, the two sets of four GND and Vcc holes at either end of the power supply are not exactly on the standard 0.1" breadboard spacing. So if .1" male connectors are mounted at either end of the power supply, it won't quite fit into a breadboard.
The description says the headers are all 0.1" which is true. However, the individual headers are not on a 0.1" grid relative to the rest of the board so mounting the power stick on a breadboard like PRT-13268 isn't really possible. Maybe the PRT-00112 type would be forgiving enough but I wanted to hard mount the stick into a prototype and that was not happening.
This is a very useful product to more easily get power to your breadboards from a variety of power bricks. I like the fact that you can easily switch between different voltages, and you have a nice convenient power switch on the board.
One suggestion I would have that would make this product even more useful would be to somehow add a way to have a passthrough of the power supply's original voltage to the board. I have a 12V, 2.0A power supply that I would like to have power an LED light strip, but use this board to deliver the stepped down Voltage for a microcontroller. I know I could use a simple Voltage regulator to manage this myself, but having a switched passthrough of the unregulated power supply for other uses would be very convenient.
As an aside, I did notice that I could kinda get what I wanted by wiring the "+" and "-" connections which were intended as a supply input out to my board. I get an unregulated connection to my raw power supply, but it isn't tied to the "On/Off" switch.
Otherwise, thanks for this useful product!
